An active library staff will present about the recent changes in university libraries. With such a thematic theme, can you listen to the graduate students who are at the forefront of the research interested with presentations that are not even "research presentations" ...? What kind of ingenuity is necessary for that? I will explain techniques that are considered to be useful for research, but not from researchers. It is a pleasure as a lecturer if you also pay attention to the "back presentation" of the second half in addition to the "front presentation" of the first half.
